This wiki is running [ikiwiki](http://ikiwiki.info) on CentOS 6 with an [RPM](http://yum.greptilian.com/RPMS/noarch/ikiwiki-3.20120202-1.el6.noarch.rpm) I rebuild from a [ikiwiki Fedora spec file](https://admin.fedoraproject.org/pkgdb/acls/name/ikiwiki).  I also had to rebuild a number of dependencies, which you can find at http://yum.greptilian.com

After installing the RPMs, I ran `ikiwiki --setup wiki.setup` on [[/wiki.setup]].

The source of this wiki ([[markdown]], mostly) is available at http://git.greptilian.com/?p=wiki.git

That's where you can find my tweaks to the default page template, for example: http://git.greptilian.com/?p=wiki.git;a=history;f=templates/page.tmpl

I order to get autolinking working (MKD_AUTOLINK per http://www.pell.portland.or.us/~orc/Code/discount/ ), I made this change to http://cpansearch.perl.org/src/SEKIMURA/Text-Markdown-Discount-0.02/Discount.xs before running `make`:

As http://ikiwiki.info/plugins/mdwn/ says, ikiwiki prefers to use Text::Markdown::Discount, if it's available.
